Drop-in passkey authentication API for fintechs and financial platforms. WebAuthn and FIDO2 infrastructure with multi-tenant isolation, secure by design, and engineered for the Brazilian market.
Overview
Passly is a passkey infrastructure platform that enables fintechs, digital banks, and financial platforms to add phishing-resistant biometric authentication to their applications without replacing their existing identity stack. Built on the FIDO2 and WebAuthn open standards, Passly delivers a turnkey passkey ceremony API covering registration, authentication, credential management, and device attestation, exposed through REST endpoints and native SDKs for web, iOS, and Android.
Engineered for the Brazilian fintech market, Passly operates as a fully managed multi-tenant SaaS on AWS, with .NET AOT compiled execution on serverless infrastructure for fast, predictable response times. Each customer tenant receives dedicated cryptographic isolation through AWS KMS customer master keys, configurable audit log retention, and webhook-based event streams that enable production-grade observability. Tenant data is encrypted in transit and at rest, with per-tenant key separation ensuring that no credential material is ever shared between customers.
Customers integrate Passly to replace SMS OTP, magic links, and password-based multi-factor authentication with passkeys, reducing authentication-related operational costs and improving login conversion rates at signup, checkout, and high-value transaction confirmation. Passly handles the complete credential lifecycle including creation, listing, renaming, revocation, challenge generation, signature verification, and counter validation, allowing your application to focus on business logic and session management. Onboarding is automated through the AWS Marketplace fulfillment flow, with technical integration completed using the published SDKs, OpenAPI specification, and reference implementations. Direct support from the Swepay engineering team is included on all paid plans.

- Multi-tenant SaaS with strong isolation: each customer tenant receives dedicated cryptographic separation through AWS KMS customer master keys, configurable audit log retention, signed webhook event delivery, and tenant-scoped API credentials. Engineered for the Brazilian fintech market with .NET AOT compiled execution on AWS serverless infrastructure for fast, predictable authentication performance.
- Phishing-resistant authentication that replaces SMS OTP, magic links, and password-based multi-factor authentication with passkeys. Transparent Monthly Active User pricing with no setup fees, no per-credential charges, and no SMS surcharges.
